I always wondered what a horizon-to-horizon mount is.
Can this term be applied to small ku-type motors like an SG2100?
We don't, but we should - you have the right idea.
Due to it's geometry, a little Ku motor and a BUD H-H mount both move a fixed number of degrees per step.
BUDs with actuators move different number of degrees per step across their range.
Likewise, actuators have more travel on one side than the other.
If the actuator is attached to the east side of the dish, you can aim further east from TS.
On that same dish, you cannot go so far the other side of TS, west (and this is the side subject to flop over)
Of course, the geometry does give reasonable travel to the weak side.
Typically an east coast user would attach to the west side of the dish.
A west coaster hooks his actuator to the east side of the dish.
If you are in the middle of the country, you choose based on which direction has lower birds of interest.
(or get an H-H and don't worry about it!).
